Description

Method and device for adjusting parameter values in a vehicle
The invention relates to a method for adjusting a parameter value in a vehicle, in which method an input gesture is detected in a detection area. The detection area here comprises a plurality of positions. The detected input gesture is correspondingly configured (or assigned) to the first or second gesture type. When the detected input gesture is assigned to the first gesture type, an input trajectory is determined and the parameter values are adjusted according to the input trajectory. When the detected input gesture is correspondingly configured to the second gesture type, determining an input position of the plurality of positions and adjusting a parameter value according to the input position. The invention also relates to a device for adjusting a parameter value in a vehicle, comprising a detection unit arranged for detecting an input gesture in a detection area. The detection area here comprises a plurality of positions. The device further comprises a control unit, wherein the control unit is used for correspondingly configuring the detected input gesture to the first gesture type or the second gesture type. The control unit is further configured to determine an input trajectory and adjust a parameter value in accordance with the input trajectory when the detected input gesture is correspondingly assigned to the first gesture type, and to determine an input position of the plurality of positions and adjust the parameter value in accordance with the input position when the detected input gesture is correspondingly assigned to the second gesture type.
In modern vehicles, in particular motor vehicles, a plurality of electronic devices are provided, which must be adjustable and operable by the driver or other vehicle occupants. These devices comprise, for example, air conditioning units, by means of which air can be introduced into a defined region of the vehicle interior and by means of which further elements, such as seat heating devices, can also be controlled. Other devices are, for example, navigation systems, driver assistance systems and communication and multimedia units, such as telephone equipment or devices for playing music and speech, such as radio sets or CD players.
Different operating units for performing operations are known. Drivers, however, often face the challenge of having to operate very complex devices. The driver must use some of his attention for understanding and operate a plurality of operating elements in such a way that the settings are set or changed in the desired manner. This usually requires very precise operating actions to be carried out, wherein, however, the driver is only allowed to move his line of sight away from the traffic situation in a short time. Here, malfunctions should be avoided, which can significantly affect driving comfort and lead to the need for further operating actions.
At the same time, the parameters of the adjustment profile must be easily understandable for the user in order to determine whether the current parameter values of the adjustment profile should be changed or suitable adjustments or settings can be maintained.
DE 102016200110 a1 discloses a device for operating a heating and air conditioning system of a vehicle, in which a finger groove is formed in a substantially flat surface, in which a sliding gesture performed can be detected.
A problem with known operating devices in the motor vehicle field is that the driver is only allowed to focus a small amount of attention on the operation, which increases the difficulty of achieving a high degree of accuracy in the operation.
The object of the present invention is to provide a method and a device for adjusting parameters in a vehicle, in which particularly accurate, simple and reliable operation can be achieved.
According to the invention, the object is achieved by a method having the features of claim 1 and by a device having the features of claim 8. Advantageous embodiments and further developments of the invention are indicated by the dependent claims.
A method according to the invention of the type mentioned in the opening paragraph is characterized in that two configurations, namely a scale configuration and an incremental configuration, can be activated for the detection region. Here, a scale configuration of the detection area is activated when the detected input gesture is correspondingly assigned to the first gesture type, and an incremental configuration of the detection area is activated when the detected input gesture is correspondingly assigned to the second gesture type. In the scale arrangement, the parameter values are arranged in correspondence with respective positions of the detection region. In the incremental configuration, the respective positions of the first sub-region of the detection region are each provided with a parameter value and the respective positions of the at least one second sub-region of the detection region are provided with an increment (increment) for incrementally changing the parameter value.
This advantageously enables particularly flexible, accurate and rapid adjustment of the parameter values for different types of input gestures as a function of the common detection region. The user can select between selecting an absolute parameter value and relatively changing the parameter value resulting from the current adjustment by selecting an adjustment gesture.
The detected gestures are analyzed differently depending on which gesture type the user uses. The function assigned to a subarea varies depending on the type of gesture, among other things. The same area of the element can thus be used for different types of input.
In the incremental configuration, the first and second partial regions are in particular different from one another and are designed as a proper subset of the detection region.
In particular, a third partial region is also provided in the incremental configuration, wherein the second and third partial regions are provided with increments of the same value having different signs. This means that the second sub-area corresponds to (or is configured with) an increasing increase of the parameter value and the third sub-area corresponds to an increasing decrease of the parameter value.
In other embodiments, further partial regions can be provided, which are configured, for example, with different increments in terms of value and/or in terms of sign. In another design, different other gesture types, e.g., different sub-gesture types of the second gesture type, can also be analyzed in different ways; in this case, different increments may be set in the same sub-area, the different increments being invoked by different input gestures.
In order to perform input gestures, the invention uses an operating object, in particular a hand or a finger of a user. In the following description, the operation object is a finger of a user, but the description is generally applicable to other operation objects such as a pen.
The term "input gesture" is understood within the scope of the present invention as a determined gesture of an operator or a determined movement performed by an operator. The input gestures can be designed in a manner known per se. The input gestures include, in particular, a click gesture, a slide gesture and a hold gesture and also combinations of a plurality of such gestures, which are carried out subsequently one after the other if necessary. The gesture is performed in a detection area, which comprises, inter alia, a surface of the detection unit. The control of the user interface by means of input gestures provides the user with particularly simple and intuitive input possibilities.
Here, the detection of the gesture is not necessarily limited to the surface. But rather gestures can be carried out in virtually any formed detection area and detected, if necessary, in different detection methods. For example, gestures in three-dimensional space can also be detected. In particular, virtual operating objects, for example virtual buttons, can be provided. For example, gestures in a spatial region can be detected in which a virtual operator control object is generated, for example by means of projection or by means of virtual reality, and the gestures are detected with reference to this virtual operator control object. In particular, the position of the gesture, the gesture trajectory, the direction of the gesture and/or the speed of the gesture are detected for this purpose.
The detection of gestures can be carried out, for example, according to optical or electronic detection methods; for detection, for example, lasers, electromagnetic fields in the microwave range or other methods can be used.
In one embodiment of the method according to the invention, in the incremental configuration, the respective position of the first partial region of the detection region is assigned the same parameter value as in the scaling configuration. This advantageously makes it easier for the user to orient in the examination area.
In the transition from the scaled configuration to the incremental configuration, the assignment of the individual positions of the second partial region of the detection region is changed only in such a way that instead of absolute parameter values, incremental relative changes of the currently set parameter values are assigned to the positions. This means that, during the transition from the scaled configuration to the incremental configuration, the assignment of the absolute parameter values to the positions of the first sub-region remains unchanged, while instead of the absolute parameter values, increments are assigned to the respective positions of the second sub-region. This may in particular result in that a transition from the scaled configuration to the incremental configuration renders certain parameter values no longer directly selectable and undetectable. In this case, provision may be made for, in order to set up the parameter value, first of all to set up the further parameter value and then to continue to change it incrementally.
The transition from the scaled configuration to the incremental configuration results in, among other things, the merging of multiple regions: the areas assigned to different values of the parameter in the scaled configuration are combined in the incremental configuration to form a continuous second sub-surface.
In another embodiment, the detection region also includes an increment region in the scale configuration in which operation causes the parameter value to change incrementally. In the transition to the incremental configuration, further positions of the detection region can now be added to the incremental region and together with the incremental region form a second sub-region of the incremental configuration. This means that the incremental areas present in the scale configuration are merged in the incremental configuration with other areas of the previous corresponding configuration belonging to the determined parameter value.
In one embodiment, the second subregion is arranged at the edge of the detection region. In the incremental configuration, a second subregion is arranged, for example, in a section to the left of the horizontally running, elongated detection region, wherein this second subregion corresponds to a stepwise reduction of the currently set parameter value. Furthermore, in one example, a third partial region is arranged in a section to the right of the detection region, in particular on the edge to the right, wherein the position of the third partial region corresponds to a stepwise increase in the parameter value. In other embodiments, the partial regions are arranged, for example, in the upper and lower regions of the vertically aligned detection region.
In another embodiment, the first gesture type includes a swipe gesture (Wischgeste). The sliding gesture advantageously enables a particularly simple adjustment of the parameter value. In this case, the adjustment of the parameter values is effected in particular in the manner of a sliding actuator, the absolute parameter values being selected by the positioning of the sliding actuator.
In a swipe gesture, the operator touches, in particular, a surface in the detection area and then moves along the operating trajectory before releasing the touch again. The operation trajectory includes a chronological sequence of the operation positions along which the operation object moves. Namely, the start position and the end position can be determined from the operation trajectory. Furthermore, a temporal course of the movement, in particular the time point of the beginning and the time point of the end of the touch, can be determined.
In this case, the control signal is generated when the touch starts at the start position, during a change of the operating position along the operating trajectory and/or when the touch is released at the end position, for example, in order to set a parameter value. The parameter value may be adjusted during performance of the swipe gesture; the parameter values then follow the path of the operator-controlled object through the detection region and change when the parameter values reach the positions assigned to the different parameter values.
In one extension, the second gesture type includes a tap gesture. This advantageously makes it possible to incrementally adjust the parameter values in a particularly simple manner by clicking as many times as necessary.
When a tap gesture is performed, in particular the operator touches the surface of the detection region and releases the touch again after a certain time, the touch position being substantially unchanged. I.e. the operating position, the touch duration and the start and end time points can be determined. In this case, the control signal is generated when a touch is initiated at the operating position or when the touch is released, for example, in order to set a parameter value. Furthermore, in particular when a hold gesture is performed, which may also be referred to as "long press" or "long press", a control signal may alternatively or additionally be generated at the end of a predetermined time interval. In performing the hold gesture, the control signal may also be generated each time an integer multiple of the predetermined time interval elapses, such that the control signal is automatically generated at certain intervals during the time period in which the touch is held longer.
In one embodiment, the second gesture type is determined as a function of the duration of a time interval during which an operation is performed in the detection area, wherein the operation is performed in particular without interruption. The user can thus advantageously use different gesture types in a particularly simple and targeted manner in order to adjust the parameter values.
For example, short clicks and longer holds can be distinguished, wherein hold gestures of different durations can also be distinguished. In the method, an input gesture of a second gesture type is recognized, for example, when a short tap is detected. In one embodiment, a hold can also be detected, according to which the parameter value is changed in further increments or jumps to a predefined parameter value; for example, the maximum, minimum and/or other predetermined parameter values can be set directly.
The detection area can be designed in a manner known per se. The detection region comprises, in particular, a touch-sensitive surface on which the detection region is arranged. The touch-sensitive surface is likewise designed in a manner known per se and can detect a touch, for example, by means of capacitive or resistive sensors.
In one embodiment, the detection region has a longitudinal extent and a transverse extent, wherein the transverse extent extends perpendicularly to the longitudinal extent and the longitudinal extent is at least twice, preferably at least three times, the transverse extent. The transverse extent extends here in particular perpendicularly to the longitudinal extent of the detection region. The detection region is thus designed to be elongated and is advantageously particularly well suited for adjusting and changing the parameter values.
The detection region can be designed, for example, as a slide bar element, by means of which the function of a slide actuator is realized. The detection area may further include an operation surface that implements a function of a push switch. Alternatively or additionally, further elements similar to the simulated rotary actuator, for example, can be provided for their function and operation.
In one embodiment, in the scale configuration, the position of the detection region is assigned to the parameter values in such a way that the parameter values lie along the scale in the detection region. In particular, in the calibration configuration, regions having a plurality of positions are provided, which correspond to the respective parameter values and which are arranged next to one another along the longitudinal extent of the detection region. This advantageously makes it possible to set the parameter values particularly simply. In the incremental configuration, in particular the individual positions of the first partial region are also assigned to the parameter values in such a way that they can be arranged along, in particular, the same scale as the scale of the scale configuration.
In a further embodiment, the highlighting is arranged in the detection region in such a way that positions assigned to the common parameter value can be detected. The highlighting may comprise, for example, a colored marking, such as a stamp, or an illumination of the surface of the detection region. For example, the continuously visible or variably visible boundary of the surface in the examination area can be designed such that the enclosed surfaces are each assigned to a common parameter value. These surfaces can therefore also be designed as operating surfaces.
A device according to the invention of the type mentioned in the opening paragraph is characterized in that two configurations, namely a scale configuration and an incremental configuration, can be activated for the detection region. The control unit is provided for activating a scale configuration of the detection region when the detected input gesture is assigned to the first gesture type and for activating an incremental configuration of the detection region when the detected input gesture is assigned to the second gesture type. In the scale arrangement, the parameter values are arranged in correspondence with respective positions of the detection region. In the incremental configuration, the respective positions of the first sub-area of the detection area are each provided with a parameter value and the respective positions of the at least one second sub-area of the detection area are provided with an increment for incrementally changing the parameter value.
The device according to the invention is designed in particular for carrying out the aforementioned method according to the invention. The device thus has the same advantages as the method according to the invention.
In one embodiment, a touch-sensitive surface is provided in the detection region, wherein a surface structure, in particular a depression or a projection, is provided in the region of the touch-sensitive surface. In this way, the region that can be manipulated can advantageously be found and manipulated particularly easily.
In particular, in this way, a tactile sensation assistance structure is provided, by means of which a user can grasp the position and the range of the detection area. For example, the haptically perceivable surface deformation may comprise a locally changing roughness. Furthermore, substantially punctiform projections or recesses can be provided on the surface, or elongated recesses or projections can be provided. More complex shapes, such as recesses with ribs extending therein or other perceptible markings, are also conceivable. Furthermore, the recess may extend straight or along a curved line.
In a further embodiment, at least one light-emitting element is arranged in the region of the detection region, wherein the light-emitting element has a light-emitting state for displaying the activated configuration. This advantageously enables a particularly user-friendly design of the device.
Such a light-emitting element can in particular display the operability in such a way that it highlights the operable region of the detection region. In particular, a plurality of light-emitting elements are arranged in the detection area. The plurality of light-emitting elements can form, for example, a light-emitting segment display device, wherein the plurality of light-emitting elements are arranged side by side in a straight line along the longitudinal extent or in a curved line.
The lighting state changes in particular when a gesture type of the input gesture is recognized and a transition between the scale configuration and the incremental configuration is made. For example, the light-emitting states of the different light-emitting elements may highlight the regions in which the absolute parameter values are arranged corresponding to the respective positions, thereby enabling the absolute parameter values to be directly selected. The light emission states of the different light emitting elements can also highlight a region in which each position is provided with an increment in correspondence and a parameter value can be changed incrementally by an operation on the position. The luminous state of the switching element can also output the adjusted parameter value, for example by illuminating a sign, a determined intensity or a color corresponding to the currently adjusted parameter value.
In a further embodiment, the device further comprises a sensor for detecting the proximity of the touch-sensitive surface in a manner known per se. When such an approach is detected, the light-emitting element can be controlled in such a way that it emits light at least at a basic intensity, in order to thereby, for example, display the position of the light-emitting element or indicate an input possibility for the user.
The parameter values relate in particular to the regulation of the temperature, the fan or the media playback device of the vehicle.

A vehicle having an embodiment of the apparatus is described with reference to fig. 1.
The vehicle 1 comprises a detection unit 2 coupled to a control unit 3. Furthermore, the air conditioning unit 4 is coupled to the control unit 3.
In the embodiment described, the detection unit 2 has a surface facing a user in the vehicle 1. On this surface, various markings are arranged, which are partially backlit by a light source, in particular a light-emitting diode (LED). Furthermore, an area having a luminous area is provided, which is covered by the color layer in such a way that the luminous area is visible to the user substantially only when the luminous area is actually illuminated, and is virtually invisible when the luminous area is not illuminated. Display devices designed as so-called black panels are used in particular here.
The surface of the detection unit 2 may be designed flat. The surface may also have recesses and/or protrusions that are perceptible to the user by a finger and that may serve as tactile aids for specifically marking certain areas of the surface. Such a tactile aid can, for example, project a touch-sensitive region of the surface, for example designed as a button element or as a slider element, or as a mechanical switch.
The detection unit 2 further comprises a film manufactured in the IML process (in-mould labeling) and post-injection molded in plastic (hingerspritz). The detection unit in the exemplary embodiment also comprises sensor elements Sa, Sb, Sc, which are designed here as capacitive sensor elements. The sensor elements Sa to Sc are arranged behind the surface of the detection unit 2 such that they cannot be seen by the user. The sensor elements Sa to Sc are designed in a manner known per se such that they can detect an operation by means of an operating element. For this purpose, the sensor elements each have a detection region, which comprises, for example, a region of the surface of the detection unit 2 and/or a spatial region arranged above the surface. In particular, the fingers of the user can be used as operating elements. In the described embodiment, the sensor elements Sa to Sc detect operation on the basis of the entry of the operating element into the detection region, on the basis of a touch to the surface, on the basis of its distance from the sensor elements Sa to Sc, on the basis of a movement in the detection region and/or on the basis of the duration during which the operating element is detected. This operation is then analyzed by the detection unit 2 and/or the control unit 3.
In the embodiment, the sensor elements Sa to Sc are arranged along a straight line at equal intervals from each other. Thereby realizing a slider element or a slide bar element along the line. The function of the slider element or slide bar element will be explained in detail below.
In other embodiments, the detection unit 2 alternatively or additionally has a touch-sensitive surface area designed in other ways known per se. The operation by the operation element can be detected by these surface regions similarly to the above-described operation manner of the sensor elements Sa to Sc.
When an operation is detected, the detection unit 2 generates, inter alia, a control signal and passes this control signal to the control unit 3. Parameter values can be adjusted, either in that the detection unit 2 itself has already processed the input (or the input content) to such an extent that it correspondingly assigns a specific parameter value to the input, or the control unit 3 performs such a processing of the input signal or control signal generated by the detection unit 2.
Furthermore, the detection unit 2 comprises light-emitting elements La, Lb, Lc, Ld, Le which are arranged adjacent to one another along a linear direction of extension in the form of a segmented display device. The light emitting elements La to Le can be controlled independently of each other by the control unit 3.
The air-conditioning unit 4 is formed in a manner known per se and in the exemplary embodiment comprises essentially a heating device for the vehicle 1, a seat heating device for the driver's seat and the passenger's seat, a steering wheel heating device, a glass heating device and a fan for introducing air into the interior of the vehicle 1, wherein the direction, distribution, intensity and temperature of the inflowing air can be adjusted.
The embodiment of the device described above with reference to fig. 1 is described in more detail with reference to fig. 2.
Fig. 2 shows a view of the surface of the detection unit 2 facing a user in the interior of the vehicle 1. The surface is designed substantially as a horizontally extending rectangle. In the upper region, button elements 101, 102, 103, 104, 105, 106, 107 are arranged side by side. These button elements are designed in the exemplary embodiment as touch-sensitive surface areas which can be actuated by touching with an actuating element, in particular a finger of a user. The touch-sensitive areas associated with the individual button elements 101 to 107 are shown by dashed lines in fig. 2. In these regions, a luminous surface is also provided, which can be illuminated by activating an LED arranged behind the luminous surface with light of a certain intensity and/or color, in order to output, for example, a status, an activation or an adjustment corresponding to the function assigned to the respective button element 101 to 107. The detection unit 2 is controlled by a control unit 3 and the signals detected by the detection unit 2 are analyzed if necessary.
Further button elements 108, 109, 110, 111 are also provided in the central and lower regions of the surface of the detection unit 2. The further button elements are also formed in the exemplary embodiment by touch-sensitive surface regions, which are indicated by dashed lines. Other functions can be called up, activated or adjusted by operating the further button elements 108 to 111. The MENU view can thus be called up on a display in the vehicle 1, for example, by actuating the button element 110 "MENU". The air-conditioning unit 4 can be turned OFF by operating the button element 111 "OFF". The air conditioning system of the air conditioning unit 4 of the vehicle 1 can be activated by means of the button element 109 "a/C", and the automatic mode of the air conditioning unit 4 can be activated by means of the button element 108 "AUTO".
In other embodiments, the button elements 101 to 111 can be designed as mechanical switches, in particular as push switches. Further, other functions may alternatively or additionally be provided in other embodiments.
In the central and lower regions of the surface of the detection unit 2, partial display devices 115, 116 are also arranged, which in the exemplary embodiment are suitable for outputting a two-digit temperature value with one digit after the decimal point. Furthermore, sliding bar elements 112, 113, 114 for adjusting the temperature and the fan level are arranged here. The individually adjustable functions of the air conditioning unit 4 are indicated on the surface by means of symbols. The slide bar elements 112 to 114 each comprise a horizontal straight line of determined length, along which a recess is designed on the surface of the detection unit 2. Behind this, covered by the surface are sensor elements Sa to Sc, by means of which a touch in the region of the slide bar elements 112 to 114 can be detected, in particular the position of the touch and, if necessary, the movement along the slide bar elements 112 to 114.
In the exemplary embodiment, the line for adjusting the slide element 112 of the fan, i.e. the fan slide 112, can be illuminated in sections by means of the light-emitting elements La to Le arranged behind said line.
An example of the level of adjustment of the fan of the output air-conditioning unit 4 by means of a segmented display device is explained with reference to fig. 3A to 3C. In particular, the embodiments of the device described above with reference to fig. 1 and 2 are used as starting points. The segment-type display device of the exemplary embodiment is arranged in particular in the region of the fan slide 112 and is controlled by the control unit 3.
Seven light-emitting areas LED1 to LED7, which can be illuminated in particular by light-emitting diodes, are arranged side by side in the example along a straight line and can be controlled independently of one another. The number of the light emitting surface LEDs 1 to 7 emitting light corresponds to the level of activation of the fan, that is, as many levels as the light emitting surface LEDs 1 to LED7 are provided. In the exemplary embodiment, a light diffusing glass is also arranged above the luminous area LEDs 1 to 7, so that the illuminated luminous area LEDs 1 to LED7 arranged next to one another form a continuous line from the perspective of the user.
In the case shown in fig. 3A, the fan of the air-conditioning unit 4 is in a deactivated state. The diagram shows the intensity of the light emission on the Y axis, while the individual luminous surface LEDs 1 to 7 are assigned to positions along the X axis. No light-emitting surface is illuminated, which is represented in the diagram of fig. 3A by the virtually invisible bars.
In the situation shown in fig. 3B and 3C, the third level of the fan of the air-conditioning unit 4 is activated. These figures show the intensity of the light emitted by the light emitting face LEDs 1 to LED7 in terms of position or in terms of the respective light emitting face LEDs 1 to LED 7. The night mode of the partial display device is activated in the case shown in fig. 3B, and the day mode of the partial display device is activated in the case shown in fig. 3C. The first three luminous surfaces are controlled in such a way that they emit light with 60% or 100% of the maximum intensity, while the remaining four luminous surfaces are controlled in such a way that they emit light with only 10% or 20% of the maximum intensity. This means that the display is carried out in the daytime mode with an increased light intensity compared to the night mode, so that the display content can be easily read also in the case of strong ambient light in the daytime, while the user is not disturbed or dazzled by an excessively high intensity in the case of weak ambient light at night.
In the exemplary embodiment, the "overflow light" from the brightly illuminated luminous surface to the adjacent luminous surface which is not illuminated or is less illuminated is covered in such a way that all luminous surfaces are illuminated at least at the base intensity. Only the light-emitting area actually used for the display is illuminated with a higher display intensity. This means that all luminous areas not used for displaying the fan level are illuminated uniformly without having different intensities depending on the distance from the luminous area illuminated with higher intensity due to overflow lighting.
In order to achieve this uniform illumination at the base intensity, it may be necessary to load the light-emitting diodes with different currents; thereby especially compensating for overflow luminescence. For example, it can be provided in the case shown in fig. 3B that the first three light-emitting diodes, namely LED1, LED2, LED3, are operated with a first current for 60% of the maximum intensity, wherein an overflow emission of light results in a certain intensity already being emitted in the region of the two adjacent light-emitting areas LED4 and LED 5. The light-emitting diodes of these light-emitting area LEDs 4 and 5 therefore operate only at a lower current than the more remotely located light-emitting area LEDs 6 and 7, in order to achieve a uniform base intensity of the light-emitting diodes LED4 to LED 7. For example, the immediately adjacent light emitting face LED4 is operating at 5% and the next adjacent light emitting face LED5 is operating at 7%, while the further light emitting face LEDs 6 and 7 are operating at 10%. In other exemplary embodiments, other light sources, in particular illuminating light into the light-emitting surface LEDs 1 to 7, can be considered, which are compensated for by suitable control of the light-emitting diodes.
The intensity and other relationships between different modes may be specified in other embodiments. For example, the ambient brightness can be detected and the light intensity of the activated luminous area can be adapted dynamically to the detected ambient brightness. Furthermore, the values of the base intensity and the display intensity associated with one another may be fixedly predefined as is the case in the exemplary embodiment. Furthermore, the base intensity may be, for example, a part (or a fraction) of the determination of the display intensity or may be determined in some other way, for example, on the basis of a physical model in which the intensity of the overflow emission is determined on the basis of the display intensity and the base intensity is then formed in such a way that the overflow emission is covered thereby.
In a further embodiment, when the fan is deactivated, the entire luminous area is also illuminated with a base intensity, which is determined, for example, as a function of the ambient brightness. The luminous surface can be used in this way as a design element and for displaying a scale "0". The user can then in particular recognize that the display for adjusting the fan is located in a specific region and/or that an operation for adjusting the fan can be carried out in this region.
In other embodiments, the light emitting surface may be used to display other parameters. The light-emitting surfaces can also be used in connection with different slide bar elements 112, 113, 114 or other display devices and be controlled in the manner described.
In addition, a greater number of luminous surfaces can be used, in particular it is possible to adjust the formation or arrangement of luminous surfaces to a greater extent than the (number of) classes. For example, intermediate levels can be displayed in this way or during operation, for example, with the aid of the fan slide 112, the illuminated luminous surface can follow the position of the operating object on the slide 112. The luminous surfaces can also be arranged in other ways, for example in a two-dimensional matrix, rather than linearly next to one another.
An embodiment of the adjustment of the parameter values by means of a slide rod element is explained with reference to fig. 4A and 4B. In particular, the embodiments of the device described above with reference to fig. 1 and 2 are used as starting points. In particular by means of the control unit 3.
The following description relates exemplarily to a slide-bar element 112, which in the exemplary embodiment is assigned as a fan slide bar 112 to a detection unit 2 assigned to a fan for controlling the air-conditioning unit 4. The method can naturally also be used for other slide bar elements 112, 113, 114 and for detecting other parameter values.
As shown in fig. 2, on the surface of the detection unit 2 facing the user, a horizontal line is arranged in the region of the fan slide 112, on the left-hand end of which a fan flag 112a for the off-state of the fan is arranged and on the right-hand end of which a fan flag 112b for the maximum activation state of the fan is arranged.
Behind the surface, a light source, in the exemplary embodiment a light-emitting diode, is arranged, by means of which both the line 112 and the markings 112a, 112b can be illuminated. In this exemplary embodiment, the line 112 can also be illuminated as a segmented display device, i.e. the light sources are arranged behind the line in a row next to one another in such a way that the individual regions of the line 112 can be illuminated independently of one another with different intensities. The adjusted level of the fan is thus output, for example, in accordance with the method set forth above with reference to fig. 3A to 3C. The markings 112a, 112b and the line 112 can be permanently visibly embossed or designed with the aid of black panel technology to be visible only when they are illuminated from behind.
The touch- sensitive areas 149, 141a, 141B, 142a to 142i are shown by dashed lines in fig. 4A and 4B, respectively. In these regions, the sensor elements Sa to Sc detect an operation by the operation target as already explained above, or detection can be achieved in other ways as well. In operation, according to the embodiment, the surface of the detection unit 2 is touched by the operation object in the touch-sensitive area. In other embodiments, the substitute touch may also be detected when the operation object is located in a certain spatial region or at a position, for example, closely above the surface of the detection unit 2.
In the embodiment, the operation at the determined position is detected by the sensor elements Sa to Sc detecting signals of different strengths according to the position of the operation target. The intensity of the signal detected by the capacitive sensor, for example, depends on the distance of the operating object into the detection area. In the depicted embodiment, the user touches the slide bar element 112 at any point or the user moves its position along the motion of the slide bar element 112. Different signal intensities are thereby detected by the sensor elements Sa to Sc depending on the current position. A position is determined from the signal strength and a parameter value is adjusted according to the determined position.
In this way, different spatial regions, in particular surface regions on the surface of the detection unit 2, can be used as regions that are separate from one another in order to detect operations in said regions. These operations can in particular also be evaluated differently depending on the respective surface region. The area of the surface can be configured, for example, as a button element having a defined response characteristic, i.e., for example, having a defined threshold value for a time interval for operation, or as a slider element having another response characteristic.
This means that the surface area in which an operation can be detected can be designed virtually only, without the need to provide its own surface area for each arbitrary area. A continuous area in which the position or the operation trajectory of the operation is detected may be formed, or individual areas in which the operation is detected when the operation is correspondingly arranged to an arbitrary position within these individual areas may be formed.
In the exemplary embodiment, it is also provided that the adjusted grade is displayed in the region of the slide bar element 112 by means of a segmented display device. This is achieved in the manner set forth above with reference to fig. 3A to 3C. When the slider element 112 is operated in one position, it is illuminated in the corresponding position and the corresponding level forming the fan is adjusted. In the exemplary embodiment, however, not only is it detected in which hierarchical region the operating position is currently located, but also the approach to the surrounding region is detected. In particular, when an operating object, for example a finger of a user, is moved in the direction of another level, this approach is detected and also displayed. The user can, for example, move his finger along the sliding bar element 112 and access the region corresponding to the next stage assigned to the fan. The closer the user is to the area of the next level, the more intense the light emitting elements arranged in that area are illuminated. When the user reaches the next area, the next area is illuminated at normal display intensity.
In contrast to known touch-sensitive surfaces, in an embodiment of the method, the parameter values are detected with fewer sensors, particularly flexibly and/or with a higher resolution. The known method provides at least one sensor element for each position that can be detected, while fewer sensors are used in the method in a particularly space-saving, cost-effective and simple manner.
Different parameters of the operation, such as a starting position at which a touch starts, an ending position at which the touch ends, and a trajectory along which the operation object moves along the surface from the starting position to the ending position, are detected and analyzed. Alternatively or additionally, the duration of the touch and/or the duration of the stay at the determined position may be detected. The direction and/or speed of the movement along the surface can also be determined and analyzed if necessary.
A plurality of operational possibilities can be distinguished, which represent in particular different types of operations for inputting or selecting parameter values and are also referred to below as "use cases". These operating possibilities can be used, for example, for button elements or slider elements in the area of the touch-sensitive surface or for mechanical switches.
The user can operate the touch-sensitive area by "clicking", wherein a time interval Δ t is detected between the start and the end of the touch, said time interval being greater than a defined threshold value t0Short: Δ t < t0. Threshold value t0For example, it may be 400ms or800 ms. The point in time at which an operating event is detected and, for example, a parameter value is changed is here generally the point in time at which the touch is released. Alternatively, the operating event can also be detected at the beginning of the touch, wherein in this case each touch has triggered a click event. Typical applications of a click are for example to turn on or off a function, to incrementally change a parameter value or to directly select a parameter value by clicking on an operating surface.
The user can also compare the threshold value t at a specific location or in a specific area of the surface1Touch is maintained for a longer time interval Δ t: Δ t > t1. Threshold value t1For example, it may be 400ms or 800 ms. This operation may be referred to as "hold", "long press", or "long press". Once the maintained time interval Deltat exceeds the threshold value t1Or when the touch is released, a corresponding hold event can be triggered. As a further condition, it can be provided that a touch at a specific location or in a specific area must be released in order to trigger a hold event; in this case, the user can block the triggering by sliding the operator control object into another area, for example, onto another button element.
Furthermore, the "hold multiple" can be carried out in such a way that the touching of the first surface area continues beyond the threshold value t1Is long and then transitions into a second surface region, then likewise exceeds threshold t1Touching the second surface area for a longer time. This makes it possible to operate a plurality of button elements without lifting the operating object, for example. For this purpose, the first button element is actuated by a "hold" gesture and the user then slides the actuating object further to the other button element without releasing the touch.
At a ratio of threshold t while "continuously holding0Detecting operation in longer time interval Deltat and for threshold value t0Detects a renewed operation for each multiple of the duration. The user can trigger several operations in this case by the user being at the threshold t0For a corresponding multiple of the duration of the hold operation.
In addition, for example, when the operation object is at a threshold value t0When a short time interval Δ t remains in a surface region and subsequently an adjacent surface region is operated, a "slip" (Wischen) can be detected as an operation. This operation can then be detected, for example, for adjacent surface regions when the touch is released, wherein, in particular, it is taken into account whether the user is at a threshold value t0In a short time interval Δ t, an adjacent surface area is touched or not held there, for example.
Furthermore, a "Swipe" (Swipe) can be detected as an operation, in which the position of the touch moves from the first area to the second area and in this case in particular traverses the other areas. The speed of the position change is also taken into account here and, for example, the parameter values may change more quickly than during sliding. A "swipe" can be detected, among other things, when the speed of the swipe gesture exceeds a threshold.
In the case shown in FIG. 4A, the fan slide bar is defined as a continuous effective slide bar region 149 that extends the entire length of the line 112 and over the adjoining markers 112a, 112 b. The position of the touch and operation can be detected within the face 149 of the active slider bar area 149. As the operator moves along the longitudinal extension of the fan slide bar 112, in particular during a slide gesture, the touched position is continuously detected and the adjusted level of the fan follows the position. For example, the lowest rank corresponds to the fan flag 112a assigned to the left area or the left side of the fan slide 112, and the highest rank corresponds to the fan flag 112b assigned to the right area or the right side of the fan slide 112. Between the left-hand region or the left-hand fan flag of the fan slide and the right-hand region or the right-hand fan flag of the fan slide, regions of the same size are distributed over the longitudinal extension of the fan slide 112, which regions are respectively assigned with a rating between the lowest rating and the highest rating.
In the example described, when the operator arrives at the position assigned to this level, the level is adjusted. In other embodiments, the adjustment of the level is not performed until the touch is released, wherein the subsequent adjustment corresponds to the level assigned to the position at the time of the release of the touch.
Whereas in the case shown in fig. 4B individual touch-sensitive face regions 142a to 142i are designed. These face areas are operated by clicking so that the user can directly select the fan rating by selecting the touch sensitive face areas 142a to 142 i.
The two outermost left-hand touch- sensitive surface areas 142a, 142b and right-hand touch- sensitive surface areas 142h, 142i are additionally joined here to form an enlarged operating area 141a, 141 b. By clicking in one of the enlarged operating regions 141a, 141b, the user can incrementally raise or lower the fan level. By continuously holding in one of the enlarged operation regions 141a, 141b, the level is gradually raised or lowered according to the time interval in which the touch is held.
In the embodiment, since the expansion of the operation regions 141a, 141b limits the feasibility of directly selecting the ranks of the fans, the lowest and highest ranks cannot be directly selected. Instead, the lowest and highest levels are reached only by clicking again or holding the respective enlarged operating region 141a, 141b continuously starting from the nearest neighboring level.
The situation shown in fig. 4A and 4B is not to be understood as a static configuration of the detection unit 2 in the described embodiment. Instead, the detection unit 2 dynamically switches between the two configurations depending on the type of operation detected, i.e. the use case detected. This means that when the user performs a slide gesture, the operation is explained as explained above with reference to fig. 4A. If the user makes a tap gesture or a hold gesture that continues, the gesture is analyzed as in the configuration described with reference to FIG. 4B.
The configurations may be combined or designed in other ways in other embodiments.
In the exemplary embodiment, it is also provided that, after a slide gesture has been detected in the region of one of the slide bar elements 112, 113, 114, the button elements 108 to 111 arranged adjacent to the slide bar elements 112, 113, 140 are locked for detecting an operation. This prevents the user from unintentionally actuating one of the button elements 108 to 111 when the user continues to move the actuating object out of the region of the slider elements 112, 113, 114 during the slide gesture.
The locking of adjacent button elements 108 to 111 or other touch-sensitive areas or switching elements takes place in certain locking time intervals. The lock-out time interval begins in particular at the point in time at which the touch of the slide bar element 112, 113, 114 ceases, and can in particular be determined dynamically, for example as a function of the speed of the slide gesture and/or the travel speed of the vehicle 1.
In other embodiments, distances from the slide bar elements 112, 113, 114 are defined within which no operation is detected in the locking time interval. The distance may also be determined dynamically, for example depending on the speed of the slide gesture, the longitudinal extension of the slide bar element 112, 113, 114 and/or depending on the driving speed of the vehicle 1. Depending on the distance, in particular, a surface region can be defined which extends over the longitudinal extent of the slide bar elements 112, 113, 114; for example, faces above or below the horizontally extending slide bar elements 112, 113, 114 are not locked thereby, while laterally adjoining face regions are locked during the locking time interval.
In another embodiment, the adjacent button elements 108 to 111 are only locked if a sliding gesture is detected at least to or beyond the lateral ends of the slide bar elements 112, 113, 114. In other embodiments, the locking of the determined face area of the detection unit 2 may be triggered by other events than a slide gesture, for example by any operation in the determined face area.
In another embodiment, the user first operates the first button, then changes his selection and slides to the other button. In this case, provision may be made for the operation to be detected only when the user releases the touch. The lock interval is then triggered. This means that the user can slide from the first button to the second button without releasing the touch in this case, and operate the second button when lifting the finger. Whereupon the lock interval begins and no other buttons can be operated.
In one embodiment, acoustic feedback is generated when an input gesture or gesture type is recognized. In particular, acoustic feedback is generated when a control signal is generated based on a sensed input. The user can thus recognize whether or not his input is received. Alternatively or additionally, acoustic feedback can also be generated when changing the parameter values. The acoustic feedback is generated in a manner known per se, wherein different feedback can be output, for example, in order to output the recognized gesture type, the adjusted parameter value or other influencing factors. The acoustic feedback can also be formed dynamically for this purpose, for example by forming the pitch height as a function of the adjusted parameter value.
An embodiment for regulating the air distribution by a fan is explained with reference to fig. 5A to 5F. The embodiments described above are used as starting points here.
In the exemplary embodiment, the surface of the detection unit 2 shown in fig. 2 comprises a button element 104, by means of which button element 104 the distribution of the air introduced into the interior of the vehicle 1 by means of the fan of the air-conditioning unit 4 can be adjusted. A display of the adjusted distribution is also output in the area of this button element 104.
In fig. 5A to 5F, the distributions are output by arrows 132, 133, 134, which are arranged in different heights with respect to the occupant view 131. The arrows 132, 133, 134 are formed by luminous surfaces that can be illuminated independently of one another, while the passenger view 131 is imprinted on the surface and is therefore continuously visible. In the exemplary embodiment, the arrows 132, 133, 134 are arranged approximately in the height of the head region, torso region or foot region of the occupant view 131.
In the illustrated embodiment, the button element 104 functions as a "Toggle (Toggle) switch". This means that a fixed order of the different settings is preset and that the following settings according to said order are adjusted in each operation of the button element 104. When the last setting is reached, a transition to the first setting in the sequence takes place, in particular, according to a periodic boundary condition. In other embodiments, the sequence can be reversed when the last setting is reached, in particular according to a reflective boundary adjustment.
In the situation shown in fig. 5A, air is introduced in the upper region of the vehicle interior space. In the case shown in fig. 5B, the introduction takes place additionally in the foot region of the interior space. In the situation shown in fig. 5C, air flows only into the foot region. In the case of fig. 5D, air flows into the head region, the torso region and the foot region of the vehicle interior space, while air is introduced into the torso region and the foot region in the case of fig. 5E. Finally, in the case of fig. 5F, the air is introduced in such a way that it is blown onto the occupant in the vehicle 1 approximately in the torso region.
In other embodiments, the air distributions may be arranged in other orders or formed in other ways.
With reference to fig. 6A to 6C, a further exemplary embodiment for adjusting a parameter value by means of a slide rod element is described. The embodiments described above are used as starting points here.
The temperature slide bar 113 comprises a horizontal, straight line 113, on the ends of which temperature markers 113a, 113b are arranged. These temperature markers are blue on the left and red on the right in the described embodiment in order to symbolize a low or high temperature. The effective slide bar regions 150, 150a, 150B, 150c are indicated by dashed lines, similar to fig. 2, 4A and 4B.
In the case shown in fig. 6A, the effective sliding bar region 150 extends over the entire length of the line 113 and over a narrow region around the line. The user may change the value of the temperature parameter of the air-conditioning unit 4 within the active slider bar area 150 by a slide gesture along line 113.
In the exemplary embodiment, it is provided that the adjusted temperature is increased when a sliding gesture directed to the right is detected. And when a leftward pointing swipe gesture is detected, the adjusted temperature is decreased.
In the embodiment, the difference of the temperature change depends on which operation track the sliding gesture is performed along. The temperature can be increased or decreased by a certain interval, for example, not more than 4 ℃, while maximally utilizing the slide bar length, i.e., when a slide gesture is performed over the entire width of the line 113. When the slide gesture is performed over a smaller distance, the parameter of the temperature is changed by fractions smaller. This means that when a slide gesture is performed, the slide bar element 113 represents a relative scale (or scale) for relatively changing the adjusted temperature.
Furthermore, in another embodiment a swiping gesture is specified in which a speed exceeding a certain threshold is detected for a sliding gesture. If such a swiping gesture is detected, the temperature parameter may be changed faster, for example by jumping to a maximum or minimum temperature or by changing a larger interval, for example twice the interval specified for the swiping gesture, i.e. 8 ℃.
In the case shown in fig. 6B, there is designed an effective slider region 150a, 150B which encloses the left or right temperature markers 113a, 113B and the left or right portions of the line 113. In the described embodiment, the operation is performed analogously as already described above with reference to fig. 4B and the enlarged operating regions 141a, 141B: the effective sliding bar regions 150a, 150b can be operated by clicking, holding or holding continuously, the temperature parameter being set thereby being increased in steps.
For example, the temperature decreases by 0.5 ℃ each time a click is made in the left area 150a and increases by 0.5 ℃ each time a click is made in the right area 150 b.
In other embodiments, the increase is carried out in succession by a plurality of step values during the holding, and in particular during the holding for a longer period of time, wherein the step values can be dimensioned, for example, according to the duration of the holding, so that, for example, the parameter is changed by a step value of 1 ℃ after the holding for the defined period of time, in order to achieve a more rapid change.
In the case shown in fig. 6C, similar effective slide bar regions 150a, 150B are designed as in the case shown in fig. 6B. However, a central effective sliding rod region 150c is now additionally provided, which is arranged between the two lateral effective sliding rod regions 150a, 150 b. In the illustrated embodiment, the central effective slide bar region 150c extends over about 20% of the length of the line 113, while the two lateral effective slide bar regions 150a, 150b occupy about 40% of the length to the right and left, respectively, of the central effective slide bar region. In the case shown here, the user can directly adjust the temperature values forming the minimum, maximum or intermediate temperature values.
In the exemplary embodiment, provision is made for the touch in one of the active slide bar regions 150a, 150b, 150c to be held for longer than a certain threshold value, to be detected as an operation and to be evaluated as a direct selection. In the embodiment, when a hold gesture is detected in the active slider bar region 150a on the left, the direct adjustment forms the minimum parameter value "LO" for temperature. Similarly, when a hold gesture is detected in the valid slider region 150b on the right, the adjustment forms the maximum parameter value "HI", and when a hold gesture is detected in the valid slider region 150c in the middle, the adjustment forms the preset parameter value 22 ℃.
Other parameter values may be selected directly in other embodiments. Furthermore, different regions, for example regions having a different number or different sizes, can be provided as effective slide bar regions 150a, 130b, 150 c.
In other embodiments, further operations may be provided for direct selection, for example, clicking on the active slide bar regions 150, 150a, 150b, 150c simultaneously, in particular with a plurality of fingers. In addition, other gestures can be provided, for example simultaneous actuation of the outer active slide bar regions 150a, 150b or actuation of the slide bar regions 150, 150a, 150b, 150c with a plurality of fingers. The determined gesture may also be used to invoke a determined function or to adjust a determined parameter. For example, a "SYNC" mode of the air conditioning unit 4 of the vehicle 1 can be activated, in which the same settings are established for different regions of the interior of the vehicle 1, for example for the driver region and the passenger region. Furthermore, different functions can be switched on or off by the same component using a specific use case.
The configuration and arrangement of the effective sliding bar regions 150, 150a, 150b, 150C shown in fig. 6A to 6C can be designed as a static configuration of the detection unit 2. However, in the exemplary embodiment described, it is provided that the detection unit 2 switches dynamically between the individual configurations depending on how the temperature slide 113 is operated, i.e. which use case is detected. If an operation by means of a slide gesture or a swipe gesture is detected, the operation is analyzed corresponding to an input in the configuration having the narrow effective slide bar region 150 shown in fig. 6A. If, however, a tap gesture, a hold gesture or a continuously held gesture is detected, it can be automatically switched to detection in accordance with the configuration of fig. 6B or 6C, in order to achieve, in particular, a direct selection.
The configurations can be combined or designed in other ways in other embodiments.
In other embodiments, the vehicle 1 alternatively or additionally comprises other devices for which the parameter values are detected by means of the detection unit 2. Such other devices may for example relate to a multimedia player or a navigation system of the vehicle 1. The input is then detected analogously to the above-described exemplary embodiments of the detection unit 2 and of the method for inputting parameter values.
The above-described possibilities for inputting parameter values can in principle be combined and adapted arbitrarily with one another. Furthermore, the detection unit 2 may comprise different operating elements, which may also be arranged differently. For example, the sliding bar elements 112, 113, 114 may extend vertically or in other spatial directions instead of horizontally.
In the embodiment, the control is realized by the control unit 3. However, different system configurations can be provided, for example, by a control device of the detection unit 2, which assumes control and/or, if necessary, evaluates the existing inputs, preprocesses them and generates control signals, for example, in order to adjust the parameter values.
